Rates and indications of caesarean section deliveries in Bhutan 2015-2019: a national review.

BACKGROUND: Bhutan has made much efforts to provide timely access to health services during pregnancy and increase institutional deliveries. However, as specialist obstetric services became available in seven hospitals in the country, there has been a steady increase in the rates of caesarean deliveries. This article describes the national rates and indications of caesarean section deliveries in Bhutan. METHODS: This is a review of hospital records and a qualitative analysis of peer-reviewed articles on caesarean deliveries in Bhutan. Data on the volume of all deliveries that happened in the country from 2015 to 2019 were retrieved from the Annual Health Bulletins published by the Ministry of Health. The volume of deliveries and caesarean deliveries were extracted from the Annual Report of the National Referral Hospital 2015-2019 and the data were collected from hospital records of six other obstetric centres. A national rate of caesarean section was calculated as a proportion out of the total institutional deliveries at all hospitals combined. At the hospital level, the proportion of caesarean deliveries are presented as a proportion out of total institutional deliveries conducted in that hospital. RESULTS: For the period 2015-2019, the average national rate of caesarean section was 20.1% with a statistically significant increase from 18.1 to 21.5%. The average rate at the six obstetric centres was 29.9% with Phuentsholing Hospital (37.2%), Eastern Regional Referral Hospital (34.2%) and Samtse General Hospital (32.0%) reporting rates higher than that of the National Referral Hospital (28.1%). Except for the Eastern Regional Referral and Trashigang Hospitals, the other three centres showed significant increase in the proportion of caesarean deliveries during the study period. The proportion of emergency caesarean section at National Referral Hospital, Central Regional Referral Hospital and the Phuentsholing General Hospital was 58.8%. The National Referral Hospital (71.6%) and Phuentsholing General Hospital reported higher proportions of emergency caesarean sections (64.4%) while the Central Regional Referral Hospital reported higher proportions of elective sections (59.5%). The common indications were 'past caesarean section' (27.5%), foetal distress and non-reassuring cardiotocograph (14.3%), failed progress of labour (13.2%), cephalo-pelvic disproportion or shoulder dystocia (12.0%), and malpresentation including breech (8.8%). CONCLUSION: Bhutan's caesarean section rates are high and on the rise despite a shortage of obstetricians. This trend may be counterproductive to Bhutan's efforts towards 2030 Sustainable Development Goal agendas and calls for a review of obstetric standards and practices to reduce primary caesarean sections.

Knowledge and understanding of obstetric danger signs among pregnant women attending the antenatal clinic at the National Referral Hospital in Thimphu, Bhutan: a cross-sectional study.

BACKGROUND: The third Sustainable Development Goal for 2030 development agenda aims to reduce maternal and newborn deaths. Pregnant women's understanding of danger signs is an important factor in seeking timely care during emergencies. We assessed knowledge of obstetric danger signs using both recall and understanding of appropriate action required during obstetric emergencies. METHODS: This was a cross-sectional study among pregnant women attending antenatal clinic at Bhutan's largest hospital in Thimphu. Recall was assessed against seven obstetric danger signs outlined in the Mother and Child Health Handbook (7 points). Understanding of danger signs was tested using 13 multiple choice questions (13 points). Knowledge was scored out of 20 points and reported as 'good' (≥80%), 'satisfactory' (60-79%) and 'poor' (< 60%). Correlation between participant characteristics and knowledge score as well as number of danger signs recalled was tested using Pearson's correlation coefficient. Association between knowledge score and participant characteristics was tested using t-tests (and Kruskal-Wallis test) for numeric variables. Socio-demographic and clinical characteristics associated with the level of knowledge ('good' versus 'satisfactory' and 'poor' combined) were assessed with odds ratios using a log-binomial regression model. All results with p < 0.05 were considered significant. RESULTS: Four hundred and twenty-two women responded to the survey (response rate = 96.0%). Mean (±SD) knowledge score was 12 (±2.5). Twenty women (4.7%) had 'good' knowledge, 245 (58.1%) had 'satisfactory' knowledge and 157 (37.2%) had 'poor' knowledge. The median number of danger signs recalled was 2 (IQR 1, 3) while 68 women (20.3%) could not recall any danger signs. Most women were knowledgeable about pre-labour rupture of membranes (96.0%) while very few women were knowledgeable about spotting during pregnancy (19.9%). Both knowledge score and number of danger signs recalled had significant correlation with the period of gestation. Women with previous surgery on the reproductive tract had higher odds of having 'good' level of knowledge. CONCLUSIONS: Most pregnant women had 'satisfactory' knowledge score with poor explicit recall of danger signs. However, women recognized obstetric emergencies and identified the appropriate action warranted.
